I absolutely agree 90% of the time. Unfortunately, I am also a dedicated elven player and am pretty much convinced that
LR is necessary against Corsairs and to a lesser extent Besiegers. I'm not saying that it's impossible to win without her, but it's very unlikely. In King block, Possessions and Conditions were meant to be transitory, and without
LR Elves have no possession removal.
Of course, against everything else she is utterly broken.
